MAKE_JOBS_SAFE with gmake

[Doug Barton]

Question,

I'm testing my ports for MAKE_JOBS_SAFE-ness, and came across this
message when building xscreensaver (which uses gmake):

gmake[1]: warning: jobserver unavailable: using -j1.  Add `+' to
parent make rule.

I have zero gmake fu, can anyone help me make sense of that? The good
news is that the build finished successfully ...
